Letters Patient No; 111,351-, dated Jennery 31, 187i.

IMPaovEMENT IN BuNe-Ex'rRAcToRsf The Schedule referred to in these Letters Patent and making part of the same.

ciently full, clear, and exact-description' thereof to',

enable one skilled in the art to which my invention appertains to make and use it, reference being had to the accompanying drawing making part of' this specication.

ing bungs, which consists of a rod or st'em connected to suit-able devices -for operating it, which rod is fitted with a peculiarly-constrncted and operating gravitating-dog or catch adapted to change position and catch under the bung after the lstem has been inserted in a small hole purposely prepared in the same.

The object of my invention is the production of a simple and reliable instrument which is adapted to extract any ti ghtly-itting bung after a small aperture has been bored through the bung for the insertion oi' the instrument, or that can be usedmore conveniently io extract the detachable central plugbung.7 for which I have made an 'application for Letters Patent, the instrument in the latter case being' inserted after the forcible driving into the barrel et' the cylindrical central plug. Y

Description of the Accompanying Drawing.

Figure 1 is` a perspective view of the instrument. with the preferred connecting devices.

Figure 2 is a vertical section of a bung'and the stem oi' the instrument, exhibiting the position of the gravi- 'rating-dog or catch on its way through the bung.

Figure 3 is a side elevation of the stem of the iustrulnent and bung, showing the position the dog occupies after passing through the bung.

Figure. 4 is a view of a more simple device for operating the puller than that shown in fig. l.

cncml Description.

A is the rest or fulcrum to which' the lever B is attached, the latter beihg pivoted or journaled at a between theA jaws of' the rest A.

The lever ,l is constructed with jaws b b', between which the eye B of the stem (l is iourualed on the pin D. u l

The stem C is slotted at c in the manner shown for reception of the gravitating-dog or catch E, which .is retained in the slot by the pin F. v

The bottom ofthe slot c is inclined or beveled to a considerable extent at c', as shown, and the dog E is beveled on one end, at e, to match, for the double purpose of 'throwing a preponderanceof weight upon the opposite end and causing it to soadjinst itself, by-riding on the inclined slot, that the heavy end of the dog assumes a position from which it can fall into the position shown in tig.

To permit oi' the automatic adjustment of thedog v preparatory to the fall ofthe same, the hole e', through the dog, is slotted lVheu the dog reaches the po! sition shown in g. 3 it rests upon the -square shoulder c of the slot. l

Although I prefer the device shown in fig. l foi-operating the puller, other devices may be employed to accomplish the simple object ot' pulling the stem O, such as ascrew, or the device shown in iig. 4, which is simply the provision of the handle G 0u a longer Stem.

Operation.

If the instrument is used to extract the central detachable plug-bung, it will be simply necessary to drive into the barrel the central plug, which is cylindrical, ci' small diameter, and consequently easily displaced, and then insert the stem O in the manner shown in iig. 2. After the dog E has passed through the bung it assumes, in the manner described, the po'- sition shown in g. 3.' 1f' the fulcrum A, which may be concave on the lower face, is then brought to rest upon the barrel, a moderate degree of' pressure by hand upon the end'of the lever B will be sufcieut to' extract the bung. If the bung is of the ordinary solid character it will be necessary to bore a hole through it of the sizeof the stem O, for the introduction ot' the instrument. The device shown in g. 4

is operated by inserting the stem a greater distance into the' barrel than that necessary for the device shown in iig. 1, and pulling the bung by driving the dog forcibly upward against the bung by means of the handle G.

Claim.

The instrument herein described for extracting bnugs, consisting of the stem VC Fand gravitatingdog E, connected, consti-opted, andoperating substantially 1n the manner and for the purpose specified.
